  3. Mute your microphone and turn your camera off.
  4. Please actively enter questions regarding the presentation. Specifically, address questions to “All participants” in the chat window. This will help the session chair in responding to questions after the presentation.
  5. After the permission of Chair, unmute the microphone and enable your camera.
    • Share your presentation material and start presentation. Click on the green "Share Screen" icon. You will see a pop-up window where you select your desktop or application.
    • If you have some videos in your slides, you may select "Optimize for full-screen video clip". Click the check box in the lower left that says "Share computer sound". Now when you are in screenshare mode it will play all computer sounds to the audience.
